I have the opposite problem. Something happened during the past few days that has disabled hyperlinks throughout my Outlook 2010, including hyperlinks within emails and hyperlinks within Contacts, such as web addresses. The error messages read, "This operation
has been canceled due to restrictions in effect on this computer. Please contact your system administrator." The restriction does not occur when I access Outloo via the website. (I am using the Office Professional Plus subscription and Office 365 Plan E1.)

How can I restore this functionality? I do not see any Trust Center settings that address this issue. It seems odd that all hyperlinks would be disabled if "there is no such built-in option in Outlook to disable the hyperlinks in e-mail messages."
